Application filed. May 16, 1917. Serial No. 168,940.

To all whom it may concern:

Be it known that I, RICHARD Gr. LEDIG, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented'a new and useful Pedal for Velocip'edes, Bicycles, &c., ofWhich the following is a specification.

My invention consists in providing the pedal proper of the pedal of avelocipede, bicycle, etc., with ballbearings on the bolt on which saidpedal proper is supported and by which it is connected with the crankarm of the velocipede, bicycle, etc., in a firm and durable manner.

The invention is satisfactorily illustrated in the accompanying drawing,but the important instrumentalities thereof may be varied, and so-it isto be understood that the invention is not limited to the specificdetails shown and described, so long as they are within the spirit orscope of the claims.

Figure 1 represents a plan view ofa pedal embodying my invention.

Fig. 2 represents a longitudinal section on an enlarged scale on line2-2 Fig. l.

Fig. 3 represents a side elevation of a detached member thereof.

Fig. 41 represents a partial side elevation of another detachedmember,and sections of adjacent portions. V

Fig. 5 represents an elevation of a bolt employed.

Figs. 6 and 7 represent elevations of detached members of the pedalproper of the device.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings z-- 1 designates a bolt, one end of which isprovided with a head having on its inner side the conical portion 2which is surrounded by the cup 3, between which latter'and the adjacentportion of the bolt 1 are interposed the balls 4:, said cup having onits inner side the reduced neck 5 which freely encircles the adjacentportion of the bolt 1, the conical surface 2 of the head of the bolt,and the shoulder 6 of the cup 3 and neck 5 serving to retain said balls4 laterally in position in the ball race formed by the said members.

7 designates a barrel which freely encircles the main portion of thebolt, and 8 designate avcup which isformed with a reduced neck'9 whichlatter freely encircites the adjacent portion of the bolt 1, it beingnoticed as in Fig. 2 that the end portions of the barrel 7 are fittedtightly on the neck 9 and 5 of the respective cups.

1O designates the pedal proper of the device, the same consisting of aU-shaped plate composed of the side pieces 11 which extend parallel withthe barrel 11 and front bend 12 joining said pieces 11. Connected withthe latter are the cross plates 13 which have openings 1 1 centrallytherein so as to fit over the necks 5 and 9 of the cup 4: and 8respectively.

On the bolt opposite to the head 2 is the tubular plug 15 which has aconical inner end 16, the latter partly entering the cup 8 and formingwith the same a ball race which receives the balls 17 which are adaptedto roll on the adjacent portion of the bolt 1, it being noticed that theconical end of the plug and the shoulder 21 formed by the cup 8 and thereduced neck 9 thereof retain the balls 17 laterally in position.

On the outer terminal of the bolt is the threaded stub 18 to which thecrank arm 19 of the velocipede is secured in any suitable manner. Itwill be noticed that the terminal portion of the bolt 1 passes throughsaid stub 18 and has its end riveted on the adJaCeHt end of said stub asa head 20 which connecting said bolt with said plug and the other partsof the device, and preventing the bolt from displacement.

The plug 15 is properly spaced on the bolt by means of the engagingshoulders 22 and 28 respectively on said bolt and the bore of the plug,the effect of which is evident.

It will be noticed that the cups have ball bearings respectively on theconical surface 3 of the bolt 1, and on the conical end 16 of th plug15, and so the barrel 7 has indirectly ball bearings on the bolt,rendering the pedal proper 10 of the pedal to rock with but littlefriction, and consequently with greatest freedom on the bolt.

The surface of the main body portion of the plug 15 is made polygonal asat 24, whereby it may be properly engaged by a wrench or otherimplement, so that the plug may be turned conveniently in screwing itinto the proper part of the crank arm 19, or for removing it therefrom,and the terminal of said body adjacent to the threaded stub 18 hasthereon the shoulder 25 against I overlaps the bore of said stub,thusfirmly which the sideof the contiguous portion of the arm 19 abuts,so as to form a tight said bolt at the o'uterterminal of the stub of theplug 15 is riveted or. headed on said terminal as at 20, and so the plugis fixed to the bolt, and the latter retained in its operative position,the device then being made up in its'entirety as a compact, firmlyunited, inexpensive, strong and durable structure.

Having thus described my invention what l claim asnew and desire tosecure by Letters Patent, is

1. In a pedal for a bicycle or the like, a bolt-like member, a pedalproper rotatably mounted'thereon, a tubular plug having a stub, saidbolt being passed through the bores of said stub and plug, the terminalportion of said bolt being secured on the outer end of said stub.
